Its just too slow paced, and taking up too many chapters before the biggest, baddest, sexiest fight. Kinda anti-climaxed the last battle actually. They should have shown this way before by Shinji recapping Aizen's past to Ichigo or something.

This probably has to be the best arc since Soul Society (well, from Zaraki's fight to the end, not the beginning). There's so many character development and a good look into how the main villian gained his nemesis.

I like this Pendulum arc too,but I kinda wanna get to the past so I can see all the fights^^
I also think there are gonna be around 5 more chapters,or there is gonna be a cliffhanger and Kubo is gonna change between past and present xDD

Actually, kishimoto could just go from 1 to what we are right now, from a diferent character angle..
Or even go back into the stop the pendulum a arc that is a flash back from the turn back the pendulum that is taking place right now and will go as a paralel world where events that should've happened didn't and we get a new name called "Shinigami Shampoo"
